Polymer modification method, method for producing modified polymer using it, and modified polymer

摘要

The present invention provides a new method by which polymers can be modified. The present invention provides a method for modifying a polymer including the step of: irradiating a reaction system containing a polymer with light to react the reaction system in a presence of a compound radical, wherein the compound radical is a radical containing one element selected from the group consisting of Group 15 elements and Group 16 elements, and a Group 17 element.
